I am happy with my XL2. Much improved over my original Pixel. The early concerns with screen issues may have merit, but I've not experienced any symptoms on my phone at this time. However, on my original XL I did experience ghosting, so I'll be keeping a close eye on my XL2.
Google does have a one year warranty covering materials and workmanship so I'm in no hurry to "Jump ship" at this time.
As a former Note 2, 4, 5 & 7 owner, I believe the XL2 is every bit as solid a phone as the Notes, and as a bonus, we have no bloatware and are running pure android.
Sweet.
